Answer:
1962.5
Step-by-step explanation:
The equation for the circumference of a circle is Area = pi * r squared. So if the diameter is 50, then the radius is 25. 25*25 = 625. Now we do 625 * 3.14 = 1962.5 So your answer is 1962.5 I hope this helps :)

What is twice the difference of a number and 6 is 5
Answer:
8.5
Step-by-step explanation:
Twice the difference of a number and 6 equals 5 is written algebraically as 2(x-6)=5, where x is the number. Solving for x:
2(x-6)=5
(x-6)=5/2
x=6+5/2
x=17/2
So the number is 17/2, or, expressed as a decimal number, 8.5
Use the Distributive Property to solve the equation.
3 = 3/4 ( b - 8 )
Answer:
b = 12
Step-by-step explanation:
First, distribute 3/4 to both terms in the parentheses:
3 = 3/4(b - 8)
3 = 3/4b - 6
Now, solve for b:
9 = 3/4b
12 = b
So, the answer is b = 12
Answer:
12
Step-by-step explanation:
3 = 3/4 x (b-8)
Distribute 3/4 through the parentheses
3 = 3/4 b - 6
Multiply both sides of the equation by 4
12 = 3b - 24
Move the variable to the left - hand side and change its sign
-3b = -24 - 12
Calculate the difference
-3b = -36
Divide both sides of the equation by -3
B = 12

1. (2, -3) → (-3, 2) reflection across both axes
2. (2, -3) → (2, 3) reflection across the x-axis
3. (2, -3) → (-2, -3) not a reflection
4. (2, -3) → (-2, 3) reflection across the y-axis
Answer:
(2, -3) → (2, 3) reflection across the x-axis
(2, -3) → (-2, -3) reflection across the y-axis
(2, -3) → (-2, 3) reflection across both axes
(2, -3) → (-3, 2) not a reflection
Step-by-step explanation:
Reflection across the x-axis:
When we reflect a point across the x-axis, it's x coordinate keeps the same value, while the signal of the y-coordinate is changed, having the same value, with different signal.
So the correct option is:
(2, -3) → (2, 3) reflection across the x-axis
Reflection across the y-axis:
When we reflect a point across the y-axis, it's y coordinate keeps the same value, while the signal of the x-coordinate is changed, having the same value, with different signal.
So the correct option is:
(2, -3) → (-2, -3) reflection across the y-axis
Reflection across both axis:
Both change the signal. So
(2, -3) → (-2, 3) reflection across both axes
Rotations:
When we have a rotation, not only the signals can change, but also the numbers, x with y and y with x. Rotations are not reflections. So
(2, -3) → (-3, 2) not a reflection
What are the y-intercept and axis of symmetry of this quadratic function? 5 Select two answers: one for the y-intercept and one for the axis of symmetry
Answer:
y intercept: (0,1)
Axis of symmetry: x=-2
Step-by-step explanation:
The y intercept is where the curve crosses the y axis.
y intercept: (0,1)
The axis of symmetry is the x value where drawing a vertical line has the left side of the curve a mirror image of the right side of the curve.
Axis of symmetry: x=-2
The required y-intercept is (0, 1) and the axis of symmetry is x = -2. Options A and C are correct.
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
From the above definition in the graph locate the value of y when x is zero,
So, in the graph, when x is zero y is 1
There is why the y-intercept of the given function is 1,
Now,
For the axis of symmetry, just draw a line with a vertex that part the function in two equal halves,
So vertex of the given function is (-2, -3), and the line that divides the function in two equal halves is x = -2
Thus, Options A and C are correct.

A verandah of width 2.25 m is constructed all along outside a room which is 5 m long and 3 m wide. Find:
(1) the area of verandah and
(ii) the cost of cementing the floor of verandah at the rate of 7 275 per m².
who answers first will be marked as brainliest iam serious no scam
Answer:
(i)The length of room = 5.5 m and width of the room = 4 m
The length of room with verandah = 5.5 + 2.25 + 2.25 = 10 m
The width of room with verandah = 4 + 2.25 + 2.25 = 8.5 m
Area of verandah = Area of room with verandah – Area of room without verandah = Area of ABCD – Area of EFGH = (AB x AD) – (EF x EH) = (10 x 8.5) – (5.5 x 4) = 85 – 22 = 63 m2
(ii) The cost of cementing 1 m2 the floor of verandah = Rs 200 The cost of cementing 63 m2 the floor of verandah = 200 x 63 = Rs 12,600

Number of bacteria samples analyze each day = 15
The equation for the number of bacteria analyzes after x days.
B = 15x
Now,
x = 1, B = 15
x = 2, B = 30
x = 3, B = 45
x = 4, B = 60

What is the value of a?
Answer:
a=22
Step-by-step explanation:
2a+2=46
2a=46-2
2a=44
a=44÷2
a=22
Answer:
a = 22°
Step-by-step explanation:
Since vertical angles are always congruent we know that 46° = 2a + 2°, therefor...
46° = 2a + 2°
2a = 46° - 2°
2a = 44°
a = 44° / 2
a = 22°

the sum of two consecutive even integers is 138
Answer:
68 and 70
Step-by-step explanation:
if the first integer is x, the next would be x + 2
so your equation is x + x+2 = 138
2x + 2 = 138
minus 2 on both sides
2x =136
x = 68
so if x is 68
x + 2 would be 70
if you add those up, im pretty sure you'll get 138
